From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tao Ma Subject: [PATCH] ext4: let getattr report the right blocks in delalloc+bigalloc. Date: Tue, 31 Jan 2012 23:58:16 +0800 Message-ID: <1328025496-3521-1-git-send-email-tm@tao.ma> Cc: sandeen@redhat.com, "Theodore Ts'o" To: linux-ext4@vger.kernel.org Return-path: Received: from oproxy8-pub.bluehost.com ([69.89.22.20]:51353 "HELO oproxy8-pub.bluehost.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with SMTP id S1753506Ab2AaP6q (ORCPT ); Tue, 31 Jan 2012 10:58:46 -0500 Sender: linux-ext4-owner@vger.kernel.org List-ID: From: Tao Ma In delayed allocation, i_reserved_data_blocks now indicates clusters, not blocks. So report it in the right number. This can be easily exposed by the following command: echo foo > blah; du -hc blah; sync; du -hc blah Cc: "Theodore Ts'o" Reported-by: Eric Sandeen Signed-off-by: Tao Ma --- fs/ext4/inode.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/fs/ext4/inode.c b/fs/ext4/inode.c index feaa82f..a5eb8c6 100644 --- a/fs/ext4/inode.c +++ b/fs/ext4/inode.c @@ -4200,7 +4200,8 @@ int ext4_getattr(struct vfsmount *mnt, struct dentry *dentry, * will return the blocks that include the delayed allocation * blocks for this file. */ - delalloc_blocks = EXT4_I(inode)->i_reserved_data_blocks; + delalloc_blocks = EXT4_C2B(EXT4_SB(inode->i_sb), + EXT4_I(inode)->i_reserved_data_blocks); stat->blocks += (delalloc_blocks << inode->i_sb->s_blocksize_bits)>>9; return 0; -- 1.7.0.4
